Make sure you get one that fits, with the riding style you described, no need for full suspension. Speed the money
on other parts, nice forks, drive train Sram X7 and up, good rims and hubs, brakes, ( disk ), just about anything but
ProMax will work okay for easy riding, try and buy cheap off Craigslist, so when you figure out what you want for sure,
you can re-sale the bike close to what you paid, and then get what you REALLY want. Hard question to answer without
knowing a lot about you or riding style etc....And you have to like it ! Richard
