I just ordered in new EVO HF 90 and I am looking to upgrade it. I spearfish for carp in lake michigan, with larger ones being over 30 lbs. Should I get a tomba kit? I am thinking I should go with a threaded shaft and breakaway tip like the mori 4" with spectra cord, but am unsure. Also, What are the best shafts to buy, and were? Should I upgrade the slider and rigging while I am at it?
