Nothing wrong with hel at all fella, banjo fittings are fine as long as everything is fitted correctly and checked after.
Bmw use alot of banjo fittings for their vanos system and oil lines and they are fine.
Hel are a good brand, price doesn't really come into it, at the end of the day I think the goodridge are overpriced for some lines and oe fittings. Albeit they are good lines had them on my 36
