87 lbs is a beast of a bow! I don't know anything about the Jaguar, but the biggest difference between a longbow and recurve is usually the grip, depending on the style you've been shooting.
Is that longbow your first bow? I'll bet you'll have better form with a lighter bow. Do you have any opportunities to attend a shoot, or go to a club and shoot different bows? That's the best way.
If you can't do that I'd keep my eye on the classifieds for a nice used bow. The new Samicks are good values also. The Red Stag 3 pc is a serious shooting bow for around $200, and I'll bet is a better shooter than the Jaguar. I also hear the Stingray is a fine 1pc.
