Strength of Brummell Splice?

[SV_Chamelea]

A full scan of the Forum for one year past didn't reveal my question ... but I thought I'd expand on this thread's base, better than starting anew.

I bought the Wand and Video, and thoroughly enjoyed making up some babystays for my trailer-26, replacing 1/8" wire stays of 5-feet each with two-ended eyesplices from a Vectran remnant. Following the video instructions for naked Hi-mod, I discovered that I MUCH PREFER brummel splicing of single braid versus my earlier eyesplicing attempt with StaSet!!!.

I later did some two-ended eyesplices in Regatta braid for short, 6' cockpit lifelines, using the simple bury w/lock stitch. That's where I discovered that I much prefer executing the locked Brummel, as it's seemingly more secure. However, I also discovered that the locked Brummel is actually quite a bit more difficult to execute in Regatta braid than the Vectran.

FIVE questions now occur:
1. Seems there's quite an art to performing two-ended eyesplicing that defines a finished length within a tolerance of one inch~!! Any hints?

2. Why is the Brummel more difficult in Regatta than Vectran?

3. Several MFGs suggest a "tuck splice" (their term) for various of their 12-strand products. It's a "weaving" technique that I'm not keen on trying ... how do they determine a favored eyesplice method, and what results are likely if I substituted the locked Brummel?

4. And how can we judge the degree of compromise we might induce by electing a different eyesplice technique??

5. How am I going to renew my SNARE, which is now looking pretty sad??
