Have a 30 ft fiberglass pole, but was thinking the section that would be attached to my Slx might not be strong enough to take weight of Slx fully extended as it would be one of the smaller sections holding the two poles together if you know what I mean??
Jubilee clips to reinforce where youd insert the pole into the sections?
Because the fibre glass we used was surplus we taped the top to 'reinforce' it, skud the pole into the sections making the harris into approx 35ft....
Ita a bit of a bodge but worked really well when we need the harris to be longer.
As long as you just push the pole up and down and limit side to side motion it should be fine.
(Now use a 45ft carbon and it is alot better so my suggestion is just an economical bodge suggestion)
