Bike improvements

Got out to the trails again today for 45ish miles. Nice, sunny day with 50 deg. temps and no wind. My rig is running great now since I made a few crucial upgrades. Gone is the aluminum switchblade fork- in it's place is the carbon version. Waayy smoother ride now and I think it is a tad lighter if that means anything. Ditched the Thompson seatpost too ( not because it is a bad post- still the best out there for most bikes!) and replaced it with a Bontrager XXX carbon variety- again, much smoother although prob. heavier- see how things even out! Last on the list was to can the BMX grips and replace them with a pair of green Ergon GX-1 grips. Those grips are great! I've been trying to get a pair for the last year but none of my distributors have had 'em in stock. Worth the wait. I've had problems with my two outside fingers and 1/2 my hand going numb about an hour into a ride since 12 hrs. of Santos this year. Once I got the angle right (critical) the grips worked great- I've got in two four hr. rides in the last 3 days with no hand problems! Anyways- the bike is riding great now- almost can't tell it is rigid until I get on the gas and it moves! Now- have to find some good wheels for it- the stockers came off a tractor trailer I think.
Anybody have any suggestions for hydration packs- let me know- My hydrapack is getting on my last nerve. It would be great to have something that keeps the water in until I need to use it instead of resembling a cropduster spraying down the trail (and me). Something with straps that one could adjust while riding would be great too!
Later-
