I loved growing the Cherry Pie, nice fat buds, super easy to trim, great bag appeal.
The GG#4 put on some weight for me bring a late starter, but very tough to trim. Sticky as fuck, but very ununiformed buds.
A Cherry Pie Glue might be a great cross if you can get the growth/shape of the Cherry Pie, with the stickieness of the GG#4, that would be a true winner.
