i shoot a recurve 50# @ 28 i order 2 dozen arrows before i had any idea about this trad thing (still dont know uch more lol) ae 150's the right spine to start tuning with or did i screw up and wast some money?

You screwed up big time! I'll take em off your hands for cheap!  

Just kiddin'..   :D   ..lol....So anyways,  I shoot a 50# Longbow and shoot the 150's cut to 30" with a 50gr brass insert and a 125gr tip and they fly good for me! I think your good with the 150's might have to play with length/tip weigh a bit! Don't cut all your arrows at once, work with one or two then get them flying good first!
