I'd think carefully about what style of play you want. You'll spend a lot of money on those markers, and end up with something heavy, bulky and of low tec operation. If you ONLY ever play in large scale woods games, you'll not be too limited (apart from the hassle of lugging them around the field)
For your £250ish budget, you could buy a second hand PMR, older EGO, ETEK, Invert Mini or DM series, and fit an electronic hopper plus bottle. All will shoot faster, be more adjustable and controllable and be massively lighter and more compact than your two choices. They will be perfectly at home in woods, but also on smaller fields and airball games.
