I'm going to be elasticating the 4 top kits of my Drennan Red Range pole, and need a little advice on my choice of laccy. The top kits are ready to take a bush with an internal diameter of 2.9mm without any cutting back. Drennan supply these bushes, plus wider ones if you want to cut your pole back and fit thicker elastic. I'd rather not cut the top sections back if I can help it. I was thinking of elasticating the kits using Nick Gilbert's Microbore elastics due to their thin diameter. I was thinking about 4-8 Blue for silvers in winter, 6-10 Pink for silvers and f1s, 12-16 Grey for carp in open water, and 14-18 Navy Blue for in the margins or when there are lots of lumps about. The thickest diameter elastic would be 2.3mm. Would there be enough clearance for that size of elastic to run smoothly in the bush with 2.9mm diameter. And does my selection of elastic strengths sound right?
