here's my take on this, from experience (I've had banshee, LT triple rate works, works dual rates, and currently elka's)
the lure of "LT" suspension looks good because of these stock shocks going for around $100-150
the problem with any stock shock, YFZ. TRX, or XYZ

, they are all single rate springs,
sprung for the heaviest rider the bike is rated for, usually in the 300lb. range.
all the compression/rebound adjustments in the world will not overcome the fact the shock is/may be sprung for a rider 100-150lbs heavier than you.
good suspension starts with a spring(s) rate matched to your weight and the type of riding intended.
a standard travel, double or triple rate, works, peps or elka shock setup specifically for you, will outperform a long travel setup with some stock, generically sprung shock.
my stock length Elka's fr and rr, rated for around my weight, have yet to bottom out on even the biggest jumps, so I never saw the need to go to any longer travel.
if you're heart is set on "LT", you'd be better off to watch for used aftermarket shocks from a YFZ or TRX, w/ double or triple rate springs, rated for around your weight, over any stock LT shock that your weight may not even be able to compress fully to actuate the longer travel of "LT"
by the time you spend $ to have stock shocks resprung for your weight, you could have just had aftermarket shocks to begin with.
definitely choose your shock/length before you have ASR build arms for them.
