Thoughts on new bigg coil

Looking for some insight for a new modified Bigggcoil secondary. As now
the secondary is 108" x 24" wound with #14 thhn wire. It sustained damage
this winter and the winding has sags in it. My idea while waiting for a
new secondary form is winding the same number of turns of the #14 wire onto
a 11" outside dia PVC form. Yes thats 108" x 11", quite a stick.
But how do you think it will perform all else being the same? Same
turns, just lower inductance/higher freq. The old secondary made 26.5
foot sparks, 21 kVAC input voltage, 120 BPS sync rotory, 0.173 uF cap. Of
coarse the primary will be modified & retuned as reqired. This it just
temporary untill the new 108 x 24
form is made. The old secondary was 90 mH, the new one will be 19 mH
approx. Same 8' toroid also to be used. Thoughts?
