maybe in the market for a new wheelset. i want to do a little research. i use the forums as research.

--1--

tubeless v tube? is it that tubeless = lighter, but more $$$, while tube = heavier but less $$$? any other significant differences?

--2--

i know i can't get a wheelset that is "cheap, strong, light," and that i can only pick two. say if i wanted cheap + light, what do you recommend? i'm a light rider (130 lbs + 10lb backpack + 30lb bike = 170lbs total), so i doubt "strong" is an issue for me, esp. since i mostly do XC. still, these won't break if i decide to take a 4' drop, right?

looking to fit a tire between 2.1" - 2.4". say my budget is under 500$

--3--

is it better to go hand built (i choose hub + spokes + rim), or is it better to just for a common wheelset? i'm talking about if a custom wheel is cost-effective.

--4--

the effect of rotational weight is more significant in the rim, since it's further from the rotational point, thus making it require more force to do a revolution, right? this means that a relatively light rim and a heavier hub is better than a relatively heavy rim and light hub?

--5--

other than the weight of the hub, are there other things i should worry about, such as special features that improve efficiency, or something?

thanks for your patience and answers!
