OK this question has not been asked of you yet, are you just coming over from shooting a compound? if so, then you WILL NOT have a 30" draw most likely loose an inch or so. Yes you may gain that inch back later and you may not.

No you will not hurt the bow shooting it with a longer draw.

I cannot help you on a recurve and spine, as I shoot a long bow

If you have someone at home to help, draw your bow and arrow, pointing same toward a target or in a safe direction. When at full draw, have the person(standing to the side of bow) mark the arrow at the back of the bow(side away from shooter) with a magic marker. Do this several times because you will have a tendancy to overdraw when being measured. Measure from the string groove in nock to the mark, this will be your draw length. Your draw length may lengthen as you stretch out the shooting muscles over time. It won't hurt to cut arrows long for this reason. I would advise to do this several times on different days to get a more consistent measurement.

If Your Draw Length with acompound is 30-31" then your draw length with a trad will be 28", i have a Bear #45 @ 28" I shoot carbon 500 with 5 " Feathers don't use plastic fletchings with a recurve.

thanx for all the advise i will be sure to measure my draw. thanx again

Here's a link for measuring your draw length.If the 60" bow is in good condition a longer draw length shouldn't be a problem.
