found some halves of white balls for bearings on my deck and it looks as if they have come out of the mainsheet block. Look like 1/4 in. Which should I use for replacement - torlon or delrin.
The block on my Sadler 290 is not marked with a manufacturer but it is half way down the boom and subject to shock loads gybing in races.
