looking for limbs

[cliff77]

Really liked the flight of 400g arrows but recently broke my Dalaa 55# upper limb. The arrow was within recommended limits, and 3rivers replaced them. Have gone to 500g but miss the 190fps I had with the 400g. Any suggestions as to more durable limbs that would fit the 21" Dalaa riser? Would also like to go up in poundage too, Dalaa's max for 66" amo is 55#.
