Compounds deliver less energy than a recurve of the same max weight. A 65 # compound is generally equivalent to a 45-50# recurve. The reason is simple the compound doesn't give the same force over its string travel, so the energy must be less. also the compound doesn't have the same sting travel as a recurve.
The weight isn't as important as energy into the arrow. Energy is mass of arrow times the velocity squared (back to Roy Weatherby thinking here). If a compound and a recurve move an arrow of the same weight at the same velocity, then they give the same energy regardless of what the max pull/weight is.
A chrono is a good test tool, if you want to get involved. Generally a recurve with light aluminum arrows having the same weight as a compound will shoot the arrow considerably faster.
IMHO the "fast arrow" thing is not important to the deer hunter, brown bear maybe. At hunting ranges 25 yds a 50 fps difference will not make better kills, shot placement will. Accuracy is far more important.
Compound crows bows are even less efficient so that a 120 # compound crossbow has about the same energy as a 65# compound or a 50# recurve. As i said earlier the length of time the force acts on the arrow is reduced by the short draw of a compound crossbow. so even though the pull weight is listed at 120# it is not even close to what a 120# recurve long bow would be, if you could draw it. I use to hunt with a 65# recurve int 1960s, that was real work and you could 'feel' every muscle in your back as you shot it. Laugh....I'll never be in that shape again in this life.
