Wads and spacers for a short 10 load

From what I read here everyone has some combination of filler they drop in the shot cup and a number are using an over shot card under the crimp. I'm using BPs PT1044 wad as that's what I can get right now. I had to add 2 1/4"felt spacers in the cup to get shot level up to good crimp height (card over). This half filled the wad with the shot well over the top of it in the hull.
My question for the veterans: Why not use a waxed card filler wad UNDER the wad column? They sealed powder charges pre-plastic wad days just fine. That would leave much more of the shot in the protective column, outta cut deformation some and some lead to barrel contact? Are there any taller base wads available? Answers? Opinions? Experiences?

3 1/2" Cheditte cut to 2 7/8
Cheditte 209 primer
30.2 gr. Longshot (what I had that would work, may not be ideal)
BPI PT1044 wad
2 1/4" felt spacers in cup
1 1/4 oz. #7
1 10 ga. overshot card
6pt. crimp or roll

Have you patterned your gun with this load? You most likely will find it patterns just fine as is, all my short 10's do. Your gun was built in an era before plastic shot cups and protective wraps were invented and should be choked accordingly.
