Brilliant thanks, ive had a play and come up with this,
 
	i used a metal straw and 25lb mono through the middle, it seems to pull the deeper at a good angle where as just the mono would tilt the deeper.
 
	think I'll crimp a key ring loop to the back of the boat for quick change.
 
	might just stick with this if it works, do like saving me a few quid
