Spring or hop upgrade?

They could do but it's a long way out of my way. They're quite close to where I work, only 30 mins on the northern line. But I'm on holiday this week and going to Romford tomorrow any way. If it does have a problem I may drive on to PAS. If it's going to cost £20 to fix at Romford though I'll get it done there as it will cost £30 in fuel and congestion charge to get to PAS.
