If you can draw it comfortably then I don't think it will be a problem. What are you trying to gain from this? Do you simply want to draw more weight for the sake of drawing more weight? Your speed will not increase enough to make a noticeable difference and your energy won't go up much either.

I certainly wouldn't spend the money to get heavier limbs, the bow you have now has more than enough stored energy to take any game on this continent.

Something else to keep in mind is that increasing your draw weight 5 lbs will effect your arrow spine. You may not notice a difference, then again you might need to re-tune your bow, especially with fixed blade broad heads. If you were a little stiff to begin with it might help. If you were on the line of being weak you might need to get new arrows, or make the ones you have shorter.

Personally, if your bow shoots well now I wouldn't screw with it. Unless you are good at tuning and like doing it. Then go for it I guess, best way to learn really.

And by comfortable to draw I don't mean you can draw without blowing a testicle. You should be able to look at your target, point the bow at the target and draw back to your anchor points in one smooth motion while staying on target. If you can't do that you are drawing too much weight in my opinion. And remember your bow is almost twice as hard to draw while sitting in a tree stand or when you are cold and tired.

I thought I could hunt with 65 or 70 lbs once. I used to shoot a lot in my yard and had no trouble drawing 70 lbs standing in a controlled environment. I took that bow hunting and after sitting for a while I got bored and decided to draw it. Guess what, I could barely get it back.

I picked up my stuff and went home for the day. Glad I didn't figure it out when a deer was in front of me.

I'm not saying any of this applies to you, just sayin' because I've been there and done that.
