I was thinking of either Redwood players, H4L hellfire pro, Phantom dark edition, B3 bespoke crown grade, Newbery Kudos2 Sps, Woodstock Airstream Players LE, Woodstock Tour De Force Players LE, m&H mh11, Spartan MC LE or Salix Pod finite.
I'm an opener and mainly look to drive through the cover and also cut and pull off length and width. If anyone has any experience with how any of these bats perform I'd appreciate the input and it would help me make a decision for the future.
Here's my experience of the brands:
Redwood - Pressed really hard, and was pretty planky.
H4L - All have been impressive performers. I can only imagine how good a Pro grade one will be!
Phantom - Only really heard good things!
B3 - Fantastic bats matched with excellent service. A bit pricey, but make a fantastic bat. Only really experienced the lower grades, which perform exceptionally. (G3 and Butterfly)
Newbery - Great bats, would consider maybe the IJC Platinum because the shape is nice!
M&H - Seen a few Amplus bats, and they are exceptional. I have a slightly altered Amplus from Bulldog, which is very nice. Lovely light pick ups, and they have exceptional response all the way down to the toe. An Amplus shape was what came to mind immediately when reading about your batting position/style.
Spartan - Can't really comment on them... Yet... But they're made by SS, who are fantastic bat makers. (My match bat and the one I've scored most runs with is a £160 SS LE)
Salix - My brother has a Pod Players from a few seasons ago, and it has an exquisite middle. Really well played in, and the bats made by Salix are stunning!
Woodstock - Could be good bats, heard some good reviews! I would go and apply for a 'sponsorship' and get a little discount from what you would pay a retailer. From what I've heard, I'm sure even the likes of
@WalkingWicket37 would get one!

You seem to have a good budget for bats, maybe the best option is to get a high grade and a lower grade from the same batmaker. If you contact Jake at Vitas Cricket, he could probably get you sorted out with 2 G1 Custom bats made by Hunts County for around £350! (Around the price of most of the bats you mentioned above!)
