well i bought some Sakuma Nite Crystal 14lb as reconmended to me by the tournament casters. Cheers for the PM`s guys - seems lovely and soft, will road test it tomorrow.
also thanks for your the rest of your views lads - But in my experiance Diawa Sensor is very poor performer for big casting.. while its ideal in the bigger 30lb+ class stuff on my Saltists or such for short range big baits and weights, heavy rock work where its abnormal thickness saves you losing fish and gear on the scears, in the thinner stuff on a 7ht mag getting full throttle, i find you can tell its a cheap and cheerful line and loves to blow up. Also its that thick, i can nearly empty my spool of it on my small reels.
Even the Diawa Tournament is thick for the breaking strain.... so i stayed clear of that also.
I have have tried the Ultima Power and Power Plus previously.. and while good in thick line on big reels, again i found it springy and proan to blow in the sub 15lb line.
But thats me done with the F1 line now.. for good.
