Backstay Adjuster for MK II

[Steve_in_lex]

I've done a lot of research on this site regarding backstay adjusters, and there are several comments about their not working well on MK II's, due to the high split of the backstay.  Has anyone with a MK II had experience, pro or con, with backstay adjusters?  This would be for tightening the forestay.  Comments/recommendations?

Thanks,

Steve
