LGW-BGI - Lady Penelope

Am due to fly to BGI next month. Have noticed to my great disappointment that Lady Penelope is being used on the VS29 & VS30 flights recently. I am no expert but as far as I can see this is a Heathrow plane and not one of the refurbished LGW ones??
I am assuming it is being used because there are more UC seats for the flights to Barbados at this peak time.
Does any one out there know if this is due to change when we get in to April/Low season?
On my last trip from BGI - LGW I was unfortunate enough to be perhaps one of the last people to fly on VTOP
!
I was so hoping to get on one of the refurbished planes!
