I'm not sure which armour will be suitable for my needs. Any suggestions are welcome. Thank you for your time. Because you have summoning Ill presume that RS gold you're an official member. This all depends what you're doing. How are you training for your strength? I'll presume you're using Slayer as it is a amazing training results, if that's the case then buy a black Mask/Slayer Helmet with a bandos chestplate/fighter Torso, Bandos Tassets. If you cant afford the tassets then of course you can just buy normal platelegs.
To wear boots, you can purchase Dragon Boots, gloves try for Barrows Gloves or if don't have them, you can get a battle bracelet. Amulets include two chocies and a fury, if you have the cash or glory if your short on money. If you are looking for a cape, there are too many options, but you should make sure you get the best one you can. If you're in the process of training strength the one thing to have is a dragon's defender. it's your top priority!
Can you sell it back in order to pay for a level objective, for example, 85 herblore? No. If he's not got funds and there's nothing to trade back. Is it possible to cheap OSRS GP earn more in the hrs spent on it? Yes. There's no way you'll have enough money from BCP in the time it takes to acquire the body.
