To those who didn't BB in GW1, how do you BB without having expensive players stuck on your bench for weeks?

This is my first season playing FPL and I used the wildcard chip this week. I'm struggling to decide whether to build the strongest possible 11 man squad with an ok bench or spread out funds to build a strong 15 man squad including paying up for a 2nd playing keeper. If I take the former approach, how or when will I ever be able to bench boost? If I take the latter approach, I will likely have an expensive bench for weeks and it'll be a headache deciding who to start. Plus, having to uxe FTs to free up funds from the bench over the weeks after boosting also doesn't seem ideal.

My mate at work said he used BB in GW1 which makes a lot of sense because he now doesn't have to worry much about his bench for 15 gameweeks (assuming he wildcards this GW). But for those of us who haven't, what's the best way to go about it?
