Chief a few thoughts/other kids/suggestions.

84 Williams
91 Schumacher (he is a Cadet)
98 I think both kids you have listed are too big for 98. I would say maybe Dryden, or someone like that.
105 Moeder (Neither Seaton or Humphrey has FS/GR much but are both very good)
112 Penka/Smith/Eck
119 Gentzler/Deshazer/Tannebaum/Seaton (logjam)
125 Cokeley/Madl
130 Blew/maybe Cokeley depending on how much he grows
135 Nitcher/Shavlik
140 Blair/Coover/Sanchez
145 Baughman/Curtis
152 Gaither/Pursel
160 Leupold
171 Keith/Wessel (Wessel has never FS/GR but a stud)
189 Grimes
215 Page
285 Vincent

Just my thougths. I added a few and bumped a few up that I don't think there is anyway they can or want to hold this weight until June.
