I came on intending to post something about tyres until I saw this thread!
I've only got one bike for most things, and even worse I've only got one set of wheels. (Can you hear the violins?) So a set of tyres needs to do me for training rides, leisure rides and an occasional TT.
I started with cheap stock Specialized tyres, moved to Specialized turbo elites that seemed like a decent upgrade and then moved to Michelin pro 3's. I ran them for well over a year, getting about 1500-1800 miles per tyre and getting very few punctures, until they were getting worn. I then moved to pro 4 races and have had nothing but trouble. I'm doing much less miles this year, mainly due to weather. The roads are grittier than I've ever seen them and in worse condition, but I've gone through at least 4 and possibly 5 tyres in just over 1000 miles.
So as you can see I'm one of those have my cake and eat it people. Happy to run good tyres all the time when it pays off for me, as it did last year, not so happy when it doesn't, like this year!
I went out yesterday morning and found a flat rear tyre, with a hole in it and logged on thinking enough was enough and I would buy some Rubino Pros. I had a triumph of hope over common-sense though and bought a pair of Corsa Evo CXIIs. I've a 25 mile time trial on Sunday and with very few miles under my belt I need all the help I can get.
I suppose what I really need to do is buy some spare wheels, put the good tyres on them and swap them over for TTs.
