Your bike looks good. I would also ignore the bottle cage 'advice'!
I'm generally happy with my Spa Ti Touring frame, which I built up as my main year-round-in-all-weathers commuting workhorse with a Columbus Carbon Tusk Trekking Fork.
A couple of things I wasn't amused by, though.
Firstly, as supplied to me, the frame arrived with a horrendously oblique-cylinder standard of head tube (non-)facing. It was unrideable, and the least worst rectification option for me was to buy the facing tool and do it myself; it was surprising how out-of-square the head tube ends were, and how much material needed to be removed at both ends. Fortunately this was successful and I taught myself a new bike maintenance skill in the process. Disappointing that the frame was sent out without being faced......maybe should have invoiced Spa for the trouble.
Secondly, the rear brake bosses are too wide apart and far too high (needing the shoes right at the bottom of the cantilever arm slots). Even with the longest spacers on my Shimano CX70 brakes and brand new thicker Shimano R55C+1 blocks, the wide separation means the brake arm action is way too far into the vertical section of the movement arc when the block gets to the rim wall. This means as the blocks wear, the degree of vertical block movement at the rim is so great that even with the shoe positioned as high as possible without contacting the tyre, it still risks going below the lower edge of the rim during braking. The fact that the highest-possible-without-touching-the-32mm-tyre position in the slot also happens to be the very bottom of the slot results in an absurd lack of range of fixing position.
The too-high too-wide bosses problem also means that, even using NSSLR STI levers, the blocks move hardly any distance at all for a large amount of lever pull, so have to be run incredibly close to the rim...in turn meaning that the slightest out-of-true wheel development that may occur results in rim rub and annoying drag. All this necessitates constant vigilance of brake wear, far more regular adjustments within irritatingly fine tolerances than should really be the case, and constant maintenance of wheel rim trueness within about 0.5mm of straight......across the four wheelsets I have ready to quickly switch in different tyres for different conditions.
Fortunately the fork has much better-positioned bosses, so the front (more critical) CX70 cantilever brake is a lot easier to set up, maintain and operate.
Lastly, the rear dropouts seem unnecessarily and inappropriately thin and delicate, and too cut-out, unlike many titanium frames I've seen, and I question how much they'll stand up to before cracking.....although no signs of that yet, so hopefully it's a groundless concern.
On the plus side:
It rides well, now the head tube has been rectified
It's quite well proportioned, and the nice sensible 72.5-degree seat angle affords getting the saddle as far back as needed on a wider range of seatposts
The welds seem pretty good/neat to the casual untrained eye
Rack mounts feature M6 threads, which seem far more appropriate than M5 - why don't all rack-capable frame designers specify this?
The 132.5mm rear dropout spacing means the frame can take 130mm or 135mm hubs easily
All the cable runs are external, with slotted guides
BSA-threaded bottom bracket shell, no press-fit nonsense
27.2mm seatpost diameter - none of the 'stiffer-is-better with higher-gauge seatposts' guff
Hard-wearing titanium finish resistant to the normal everyday commuting knocks and corrosion possibilities
Lighter than the steel equivalent (good for commuting, even if less important when used as a fully-loaded tourer)
OK comfort-wise (noting that all the 'magic carpet ride silky smooth, eradicates road buzz' journalist drivel and marketing nonsense associated with many titanium frames is.....drivel and nonsense)
Overall, I'm reasonably happy with it, but I shouldn't have been lumbered with the head tube problem, the rear brake issue is pretty irksome but manageable, and the frame functions well as an all-year all-weather commuter. My next addition to the commuting stable, though, currently in development, will feature Shimano hydraulic disc brakes to get away from the rim wear/replacement annoyances and constant cantilever monitoring/adjustment and wheel-trueness-checking exercises (and for nicer braking action). The Spa will then be re-assigned to mainly dry day commuting (and stand-in duties for the new commuter if I'm servicing that) to reduce the rate of rim and block wear.....hopefully enough to eke out the current rim-brake commuter rims until I no longer commute.
