New Hop-up or Upgrade Stock?

[bareass]

Hey all
i'm thinking about buying a new tightbore barrel and hop-up. wondering if i should buy a one piece, or just upgrade the stock hop-up from my SRC M4.
i'm not too keen on cutting the body to fit the new hop-up

Firstly, do you have air leak issues with your current hopup? Is it broken or not working well enough that new new rubber would be worthless?

Now, I have done the 2 piece to one piece mod and if you are careful, you can make it reversible. You only need to dremel out a small portion to make the one piece fit.

Personally, I would and have swapped it for a one piece as well as installing a new rubber and TBB but that's me.

so one piece is the way to go then?
anyone else?
