You can use the wheat if you want, I probably wouldn't. Strisselspalt is a great finishing hop when fresh for pilsnesr style beers. I'm not much of a fan of Perle (kind of minty to me) but I know folks who LOVE them. Saaz is hit or miss, I don't like them myself thought I'm a huge fan of Pilsner Urquel if fresh. Ahtanum - that's a citrussy type hop. And not one I care much for. I'm not very familiar with cluster of of late.
