I just swapped out my Ground Control sleeve over kit for B&G springs with bumpstops. Great drop and the ride isn't harsh at all, close to OEM to be honest. Definitely worth considering for the price. In all honesty you will never adjust the sleeve kit most likely, so why pay extra... unless you will adjust it, then by all means.
Retains EDC and cost me much less than sleeve kit, said and done... Very happy customer.
