I was shooting 70 compound and started with 46#@28" curve. I went to 50 real quick. I shot a lot of them in the mid 50’s when trying them, but that was too much for high volume daily shooting. There are a lot of muscles involved I shooting a trad bow, and even your fingers need to work up to weight I think. Now I found my 28" draw is a 29+" draw so the 50 would have been to heavy to start if my form was correct. Check out the form clock and get a buddy to measure you so you can get an idea of what your draw should be. That way if you are a 29 or 30" draw you will not be over bowed when you pull 3-6 more pounds than the 28” rating. Use one of those real light draw length bows and measured arrows with correct form clock form.
There are many bows that are short with long smooth draw lengths. However, I would and did get a good used bow 60" to start. I should cover you on draw length. 60" is a good all around bow for a curve. I would start with a curve for more of a compound grip. Also I would get a nice TD like a predator for a little weight to help with the change. Post up what you are considering buying and others can let you know how it will work for your draw length. There are many good used bows you can shoot and then trade or sell with little or now loss.
I started messing around about a year ago looking and trying stuff, along with shooting my old curve from when I got started 30 years ago. I went to a shoot, show, and found TG members in the area to shoot bows. I got a good starter weight used one about 9 months ago after I had a better idea of what was working for me at the time. I have had about 6 now and have two I am shooting. I am shooting 55 and 57 @ 29” right now and shooting them comfortably. It took a lot of shooting to work up 10# of draw. The first 5 was not too bad, but the next 5 took a little more time so plan to go through a couple bows getting you weight up, and there is no harm having a lighter weight starter and continuing to shoot it when you get you next higher weight bow. I have always had two as I worked up.
