Good Morning Glen. I would still consider a lightened flywheel (Stock 28lbs, lightened 22lbs) I had one in the V-8 RX-7, never saw a disadvantage, just a quicker revving 302, no slipping of the clutch to get moving (Wide ratio Tremec World Class T-5) Of course that's just my $.03 Buddy. Cheers Tom.

Tom is right. My aluminum flywheel is less than 20 lbs. and I love it. Yes, I know I have a big FE with a 3.54 rear, but it really is not a whole lot different taking off from a stop than driving any other car with a clutch. It might even bit a little safer because it revs down faster not having the stored energy.

Glen,

You may not have many options for the flywheel and clutch combo. I had to replace the flywheel, clutch and pressure plate on the race car and there are very few manufactures that make one for the Toploader input shaft. Most of them are setup for Tremec transmissions.

McLeod still offers a combo for the Toploader. I used quartermaster last time and they no longer offer an option for a Toploader.

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
