layers for a hybrid

hey everyone,im thinking of putting 1 layer of 4 oz and 1 layer of 6 oz on the bottom and on the deck im putting 2 layers of 4oz and 1 layer of 6 oz ....its for a hybrid board. Will it be strong enough or will i risk snapping the board? Do i need more layers? i appreciate the help

sounds like a bit much, but I have a friend who glasses heavy, and fixes his dings right away, and his boards last FOREVER, so maybe that's a good thing!

Here he is riding a board that is TWENTY YEARS OLD!  - glassed something like you're planning.  Its heavy, like a wood board almost, but he loves that thing.  He says when he finally gets around to making a new one, he's gonna make the exact same shape LOL.
