Don, You might be interested in my other post under 17-20 jacket question, we are planning on making 20's as we have had enough interest to make production #'s hope this eases some of the pain. Forecast next late spring hopefully....
p.s. not so sure about j4 making most jackets used at this time they couldn't give away the short 6's they ran early summer. we can not make fast enough as quick as they are in they are sold mostly in advance, it was bound to happen j4 priced themselves out of market.
