All input on flywheel mass appreciated

There's a "however" though....so here's my thinking:

My differential ratio is 2.92, and my Toploader's highest ratio (4th gear) is of course 1:1
A popular/typical choice for many has been a Tremc TKO gearbox with a diff. ratio of 3.54

Comparing these two setups shows my WR TL overall first gear ratio at 8.12:1 whereas with that TKO and 3.54 combination, the overall first gear ratio is 10.16 - so, significantly higher for mine.
Further (but not flywheel mass related), comparing top gear ratios for both combinations results in 2.92 (WR TL) and 2.90 (TKO600)

My point is that for easier starts, for me, a standard mass flywheel is a better option. Also, I have learned/experienced advice that a standard mass flywheel is the way to go.
So ....at this point, and having weighed up the valued advice from my learned friends here, a standard mass flywheel it is

Cheers!
Glen
