Just looking at specs and never fished the blackhole 450g. I would say the HTR 6'0 Composite Raw would be pretty close if you cut the bottom off making it the 5’2” length of the BH450g. Remember this is only going on specs. Rod action will differ depending on material and rod wall thickness etc. Look over the Thrasher blanks and click on the ones you think will be close and compare the specs. They list all the specs and how much weight is hanging off the tip for a little bit of a visual with the bend.Which thrasher blank is comparable to the blackhole 450?
