Re: .."mostly I was just tearing [the grips] off which worked fine." - DandyDan
It suddenly dawned that it won't be necessary to remove the whole grip on any of these poles to add an extension. Just cut the light foam extension off the discount poles I have, remove it if possible, maybe with boiling water, and slide it up the top section of the LT4s, Locus CP3s or Fizan Compact ULs until it mates with the original grip. Did this before with heavier golf club grips - should have been obvious. The golf pro has a secret formula for sliding the grips on - think it involves mineral spirits - may need to check with him again to try to pry out the exact formula (What turns mineral spirits milky white?).
All that is needed is to know the outside diameters of the top sections of these poles to be sure that the extension that fits over a 5/8" tube will fit. Alas, none of the companies have answered emails - probably figure they are just flak from some BPL gram weenie nut - OK, 2 out of 3 ain't bad.
If any of you who have the LT4s, Locus CP3s, or Fizan Compact ULs would be kind enough to measure the outer diameter just below the grip and post same, it would be much appreciated.
When the extensions are installed, promise to post pix and the resulting total weight.
Haven't decided yet on the pole, but leaning toward the Fizans because the 7001 alloy will bend before breaking, they are only an ounce apiece heavier than LT4s and about the same weight as the CP3s, and all who have them appear to say their twist locks actually work without slippage.
